John Cooper Works
More Factory Power for Your Cooper S
BMW hired the legendary John Cooper Works Company to develop the first factory authorized power upgrade for the Cooper S.
The package was designed for the global market and sold exclusively through MINI dealers and will be covered under MINI's comprehensive new car warranty.
The package includes a reconfigured cylinder head, uprated supercharger along with special engine electronics and a performance exhaust.
This enhancement takes the regular 163 hp MINI Cooper S to over 200 hp.
For existing USA MINI owners, the package can be retrofitted to their current MINI Cooper S. The complete package comes with an MSRP of $4,500 plus dealer installation of around $1,000.
High Performance Parts
Performance is at the heart of the MINI Cooper S and the John Cooper Works Package takes this philosophy one step further. The cornerstone of the package is an enhanced Eaton supercharger with specially coated vanes that generate increased flow pressure. The unit comes with a new pulley design that allows the unit to spin at a higher RPM, generating an increase in power.
A high performance head is also a key ingredient. The modified head has improved port flow and has been especially designed for the increased compression and heat produced by the supercharger.
The package also includes a reprogrammed Electronic Control Unit (ECU), which manages all engine control functions including airflow, combustion, fueling and spark advance.
The enhanced ECU has been recalibrated to optimize power output and drivability, resulting in a lively throttle response and increased acceleration in the mid-range torque band.
Also included in the package is a stainless steel sport exhaust system. The system is a parallel-flow, low backpressure system with superb interior and exterior noise quality. The system adds a throatier, more powerful exhaust note has distinctive looking twin chrome exhaust tips.
With the package, power is increased to an impressive 200 bhp at 6950 rpm from the same 1.6 liters of displacement. In comparison, the already impressive MINI Cooper S produces 163 bhp at 6000 rpm in unmodified form. Torque is also up, rating at 177 foot-pounds at 4,000 rpm for the equipped car versus 155 foot-pounds at 4,000 rpm for the unequipped car.
The John Cooper Works equipped MINI Cooper S sprints from 0-60 in an improved 6.5 seconds with a top speed increased to 140 mph. This compares to a 0-60 time for the unequipped MINI Cooper S of 6.9 seconds and a top speed of 135 mph. The performance upgrade with the John Cooper Works package is very noticeable in all driving conditions and is an ideal compliment to the superb handling and chassis dynamics of the MINI Cooper S.
Visual cues are understated and will appeal to the MINI enthusiast. A unique chrome John Cooper Works badge adorns the rear deck lid and, when raised, the bonnet reveals a visually appealing silver intercooler surround with John Cooper Works logo. An individually numbered valve cover plaque tops it off and commemorates the exclusivity of this special package.
Cooper Works or Self Tune?
The biggest advantage of the Works Package is the retention of the factory warranty. So if you are worried at all about you engine warranty...GO for the WORKS Package!
However, if you value performance per dollar (sometimes that is dictated by your budget), then you can get more power for a lot less dough by installing a cold air intake, a high header and exhaust, a smaller supercharger pulley, and some engine management (like the Conforti Shark Injector).
All said and done, a Self Tune will cost you about $2300 plus install versus $5,500 (including install) for the works package.
Power for the Self Tune should be about 205-210 hp versus the 200 hp for the works package.
If you decide to self tune your works package, it is nice to know that you already have a better head and supercharger to start with.
